LOOSE-BACK BOOK.

Specification of Letters Patent.

Patented Aug. 1'7, 1909.

Application filed March 15, 1909. Serial No. 483,558.

To all whom it may concern:

Be it known that I, CEDRIC CHIVERS, a subject of the King of GreatBritain, residing at Brooklyn, New York, United States of America, haveinvented certain new and useful Improvements in Loose Back Books; and Ido hereby vdeclare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains tof make and use the same.

This invention relates to the loose or throw-off-back method of binding,and the invention has for its obj ect a quick and economical mode ofattaching such loose back to the book which will give it increasedstrength as compared with the modes heretofore employed and will insurestraight alineinent of the edge of the back of the book.

In carrying the invention into practice, the end paper of the liningpapers or finishing sheets have sewn with them a loose piece or piecesor tab or tabs of jaconet or the like material which are pasted onto theinside of the loose back, or may carry strips of brown or other stoutpaper or the like which latter are pasted onto the loose back. The loosestrips would in the usual course interfere with the tapes to which thesignatures are sewn and would prevent them from being pasted to the sideboards, but'this is overcome according to the invention by passing thetapes through holes in such loose pieces so that said tapes may bepasted between the lining papers and the boards or be otherwise attachedto the boards. y

The invention will now be described with reference to the accompanyingdrawings, in which Figure 1 is a transverse section of a p0rtion of abook with the signatures, end and lining papers and loose back assembledin accordance with the invention, but without showing any stitching;Fig. 2 shows a portion of same with the parts in a different positionand stitched; Fig. 3 is a detail of Fig. 2; Fig. L is a rear elevationof a portion of the book with the loose back partially broken away; andFig. 5 is a sectional elevation of the loose strip of jaconet combinedwith the paper strip sepa-rated and shown in the position it has assumedin Fig. l, one of the usual tapes being shown passing through a hole insame.

Like letters of reference indicate like parts in the several views.

a is the book, which may be composed of any number of signatures, arethe boards, 0 is the loose back, usually of leather or cloth and havingextensions c1, onto which the boards Z9 I) are pasted, and CZ Z are thefinishing sheets or lining papers. rlhe front and back of the book aresimilar and therefore only one need be described. Beside the liningpaper Z there is as usual an additional sheet e. Each of the sheets d,c, has four sides d1, cl2, cl3, d4, and el, c?, e3, et, respectively.The liningpaper Z is strengthened at its fold or hinge by a piece ofjaconet f, which is pasted onto its sides d1 and d4.

Overlying the strengthening piece of j aconetf, on the sides nearest tothe book, is the piece or tab of jaconet g which in this case carries abrown or like paper strip 7i. rThe end paper e is strengthened on itsfourth side cl by a strip of aconetc' and the edge or margin of the sidec1 thereof nearest to its fold or hinge, is pasted to the adjacentsignature of the book, the paste being represented at y'. The sheet eand its strip c' are then sewn to a few signatures of the book in thewell known way, as indicated at 7.: in Fig. 3, and also in Fig. 2, afterwhich the side e4 of the sheet is pasted to the adjacent side Z1 of thelining sheet Z with the jaconet strip z', a portion of the strip g andhalf of the strip shut in between them. l represents another line ofstitching, which passes, in this case, through the part (Z3, Zt of thelining paper l at the fold and through the nearest signature orsignatures, and which thus takes up the stitching by which saidsignature is secured to the tapes m, which are near the top and bottomends of the book and at the middle or other desired points such tapes asusual passing behind the signatures, and being in direct contacttherewith by the usual stitching through the signatures. According tothe present invention said tapes m are passed through openings p (Fig.5) in the aconet strips g and the ends of the tapes are pasted to thelining sheets, or rather to the jaconet strips f, between the outermostsides d* of said sheets and the boards Z). The brown paper or likestrips 71 or the tabs g where such paper strips are not used, are thenfolded down over the back of the signatures and pasted to the looseback. Of these strips z., or tabs g, one may be wider than the other, asshown, and may underlap the narrower one. The backs of the signaturesmay be covered as usual with any reinforcing strips which may bedesired. Last of all, the sides (Z4 of the lining papers are pasted tothe boards b, b and the side c4L of the end paper c is pasted to theside Z1 of the lining paper CZ.

The invention is net restricted to the precise order of carrying out theabove operations, which may be varied more or less as desired.

lt will be observed that the lining carry the loose strip by a line ofsewing so that when the strip is pasted firmly to the back it forms anattachment to same which is sewn to the book signatures so that ineffect the loose back may be saidA to be sewn tothe book.

l hat l claim is zl. A bound book, comprising a series of signaturesconnected together in the usual way, lining papers placed in front andback of said series of signatures, and having their folds reinforced'and stitched to the adjacent signatures, a loose back, perforated 'tabsof jaconetor similar material' secured to said lining papers and tovsaid loose back, and tapes secured to said lining papers and saidsignatures, and passing' through the perforations in said tabs,substantially as described.

Q.
